Abstract: The combination of multiple, i.e., two or more, gene delivery vehicles (“GDVs”) with a pharmaceutically acceptable carrier or diluent to provide a pharmaceutically acceptable composition, and the administration of such a composition to an animal. The invention provides numerous advantages over previous methods of treating diseases or other pathogenic agents that included the use of a GDV, such as control of the level of expression of different genes carried by different GDVs, for example when it is preferred that the elicited response be predominantly against a gene product from one GDV, or if an immediate response is required from one GDV's gene product and a delayed or priming response is required from the other.
